DELBERT L. GALLUP, OF GOLEGROVE, PENNSYLVANIA.

DOOR-OPERATOR.

Application filed August 9, 1916. Serial No. 113,992.

To all whom it may concern:

Be it known that I, DELBERT L. GALLUP, a citizen of the United States,-residing at Colegrove, in the county of McKean'and State of Pennsylvania, have invented certain new and useful Improvements in Door- Uperators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to door-operators particularly adapted for installation in motor-vehicles for opening and closing doors thereof by operation of a member located conveniently to the drivers seat, but the invention is not limited to such use, as it is susceptible of adaptation to other doors and the like.

It is an object of the invention to form and arrange the parts of a device of this character in such manner that a door may be unlatched and opened on movement of a primary actuating part and closed and latched upon reverse movement of the actuating part, and it is adapted for use with doors opening either toward the front or rear of a vehicle in which it is installed.

\Vhen read in connection with the description herein,the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawings forming part hereof, wherein an embodiment of the invention, as adapted to a passenger motor-vehicle, is disclosed, for purposes of illustration.

\Vhile the disclosures herein now are considered to exemplify a preferable embodiment of the invention, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as it is obvious that alterations and adaptations within the scope of the claims can be made without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the drawings, of which Figure 1 is a side elevation illustrative of an adaptation of the invention to doors opening toward the front, certain parts being broken away; Fig. 2 is a similar view illustrative of an adaptation of the invention to doors opening toward the rear; Fig. 3 is a plan view of the adaptation illustrated by Fig. 2; Fig. 4: is a sectional view on the line 4-4, Fig. 2, the door being closed; Fig. 5 is a similar View, the door being open; Fig.

6 is a sectional View on the line 5-5, Fig. 2; F 1g. 7 is a View of the operating-shaft and arms thereof; Fig. 8 is a transverse sectional view on the line 88, Fig. 7; and Fig. 9 is a detail view, partly in section, showing the connection between the latch and its operating-lever.

Having more particular reference to the drawings, 9 designates a motor-vehicle, having a front or drivers seat 10, a rear seat 11, hollow side walls 12, and outwardlyopening doors 1?) hung to the side walls by hinges 14 and closing doorways in the usual positions in advance of the rear seat. Set in the side of each doorway opposite to that at which the door is hung is a recessed latchkeeper 15.

7 Each door has set into its edge opposite to the keeper 15 a guide-plate 16, and within the door and secured to one of the walls thereof there is a guide 17, the plate and guide, respectively, constituting guides and supports for the outer portion of a latch 18 and a stem 19 thereof extending inwardly therefrom. There is a shoulder 20 at the place of juncture of the latch proper and its stem, and around the stem and between the shoulder and guide 17 there is a coil-spring 21, which has a tendency to move the latch outwardly and into engagement with the keeper 15 and thus hold the door closed. A handle 22 extends upwardly from the latch through the upper edge of the door for manual operation of the latch, and on each side of the handle and secured to the doorwallsthere is a stop-pin 23, which on contact of the handle therewith limits the movement of the latch and one of which operates to prevent sprin 21 from pushing the latch too far outward y.

The latch 18 is formed with a longitudinally-disposed horizontal slot 24, in whichis freely movable a stem 25, having a retaining-disk 26 thereon. The latch at this place is straddled by the forked upper end 27 of a lever 28 pivoted intermediate its ends and having in each limb of its upper fork a slot 29 in which the stem is freely movable. The disk 26 lies between the latch and one of the limbs and retains the stem in place, and the slots permit the swinging movement of the lever required for longitudinally moving the latch. The other or lower end of the lever has a slot 30, and in the slot is freely movable a pin 31 carried by a forked leverstraddling end 32 of a slide 33. The slide 7 intermediate its ends has opposed shoulders 34, between which it is enveloped by a supporting-guide 35. The slide extends shghtly beyond the hinge side of the door, and there it is hingedly connected to one end of a slide extension 36. At its other end the slide-ex tension has a pin 37, which is movable in slots 38 in the limbs of a forked upper end 39 of a lever 40, whereby the slide-extension and lever are pivotally connected. The lever 40 is pivoted intermediate its ends, and it is connected with means, now described, whereby it is moved by actuation of a part convenient to the drivers seat to open and close the door with which it is associated.

As supports of a door-operating foot-lever arrangement, hangers 41 are secured beneath the floor of the vehicle to the sides thereof fairly close to the drivers seat, and an opcrating-shaft is carried by these hangers. The operating-shaft includes a rotatable section 42 and a non-rotatable section 43 with abutting ends. The outer end of the section 42 is journaled in one of the hangers 41, and the outer end of the section 43 is held in the other hanger by a pin 44 passing therethrough. The abutting end portions of the sections are enveloped by a sleeve 45 held fast on the rotatable section 42 by a setscrew 46 or the like and rotatably movable with respect to the non-rotatable section 43. The portion of the sleeve enveloping the section 43 has clutch-teeth 47 formed in its end. A collar 48, having at one end clutchteeth 49 facing those of the sleeve 45, is loosely mounted on the shaft-section 43 with its other end in abutment with one of the hangers 41, and collar 48 has a radiallyextending arm 50. A clutch member 51, rotatably and axially movable with respect to section 43, is positioned on that section be tween the facing clutch-teeth of the sleeve 45 and collar 48, and at each end it has clutch-teeth 52 arranged to engage those of the sleeve and collar. The clutch member 51 carries an upstanding arm 53 extending through the floor of the vehicle, and on the upper end of this arm there are oppositelypositioned wings 54 extending substantially at right angles with respect to the operatingshaft. Therelative proportions, positions, and arrangement of the parts are. such that the clutch-teeth 52 on axial movement of the clutch member 51 may be entirely disengaged from either of the other set of clutch-teeth, but not simultaneously from both sets, and they may engage both sets simultaneously. A collar 55 is held fast, by a set-screw 56 or the like, on the rotatable section 42, and an arm 57 extends radially from this collar. I

A forked end 58 of a coupling 59 is connected by a pin 60 to the free end of each of arms 50 and 57, and at the other end this couphng is recessed and interiorly screw threaded and receives a threaded end of a rotatable stem 61, which is held against rotation by a lock-nut 62 thereon bearing against the end of the coupling. The turnbuckle at its other end is connected with an operating-rod 63.

In the case of rearwardly-opening doors, as exemplified by Figs. 2, 3, 4, 5, and 6, the lever 40 of each, connected to the slide-extension 36, is sufficiently long to extend below the floor of the vehicle, and at its lower end it is connected directly to one of the operating rods 63 by a pin 64. In the case of forwardly-opening doors, as exemplified by Fig. 1, where movement in the opposite direction of parts immediately associated with the doors is required, the pin 64 of an operating-rod engages the lowerend of an interlnediately-pivoted lever 65 having at its upper end connection with a forked lower end 66 of the lever 40, there being a slot 67 in each of the limbs of the fork in which a pin 68 of the lever 65 is received.

When it is desired to operate both of the doors simultaneously, the clutch-member 51 is brought, by side pressure of a foot, to such position of axial adjustment that its teeth, which are suficiently long for the purpose,

are in engagement with those of both the sleeve 45 and collar 48, when arms 50 and 57 with which the operating-rods 63 are connected are subject to movement. One of the wings 54 then is pressed downwardly by the foot, the collars 48 and 55 are rocked on the shaft, and thereby the arms 50 and 57 are swung and the latch mechanism and doors operated in one direction through the con necting instrumentalities. By the same means, pressure of the foot on the other wing 54 will cause reverse movement of the parts.

It being desired to open one or both of the closed doors, and pressure being applied to the proper wing 54 to move the parts in opening direction, the slide 33 of a door is moved inwardly of the door until its shoulder 34 at the hinge side of the guide 35 engages the guide, whereby further sliding movement of the slide is stopped. The parts are so relatively arranged and proportioned that during this sliding movement the door has been unlatched by withdrawal of the latch from the keeper through the in strumentality of the lever 28 operatively connected with the slide and having its stem 25 in the latch-slot 24, the stem normally resting against an end of the slot when the slide is in its median position. Pressure being continued against the slide-extension by the lever 40, the door is pushed open, in view of the fact that the pintles of outwardly-opening doors are at or beyond the outer edge thereof and the slide housed within the door is removed from the plane of the pintles, the hinge connection of the slide and slide-extension permitting the incident swinging movement between those parts. The formation of the parts is such that by the time there has been suflicient movement to release the latch, the hinge connection of the slide has moved to the edge of the doorway, where there is no interference with the relative swinging movement of the slide sections during swinging movement of the door. The slide projecting outwardly of the door acts as a lever in swinging the door outwardly after the first movement-thereof from latched position. Upon exertion of force against the parts by pressure on the other wing 54, the slide-extension 36 pulls on the projecting end of the slide, which latter acting as a lever pulls the door toward closed position. Then the door has come nearly to closed position, and the pull of the slide-extension, of course, being continued, the slide is moved in a direction opposite to that given to it on the initial actuation to open the door until the opposite shoulder 34 engages the guide 35 and stops further sliding movement. The continuing pull on the slide completes the closing of the door. During this movement of the slide in its guide, the lever 28 has been moved to release the retractive hold of the stem 25 in the end of the latch-slot 2i, and the latch is pushed outwardly by the spring 21. The latch-slot is sufliciently long and so placed that the stem 25 on the lever will not interfere with retractive movement of the latch, even when the parts are in the extreme positions they assume during the closing movement, so that the latch is free to move on striking the keeper at completion of closing movement of the door and also when it is desired to operate it by the handle at any time. If the spring 21 is sufliciently strong to cause, after cessation of opening exertion on the parts on completion of opening movement, movement of the slide to median position, that is immaterial, because there is still sufficient projection of the slide from the door-edge to afford the required leverage for closing the door.

Having thus described my invention,;

what I claim as new, and desire to secure by Letters Patent, is

1. In combination, a fixed keeper, a hinged swingable door, a slidable latch housed within the door having a longitudinal slot and arranged to engage said keeper, a spring normally maintaining said latch in engaging position, a stem in said slot, a lever pivoted intermediate its ends having a forked end formed with slots in which said stem is positioned, a slide connected with the other end of said lever and normally extending beyond the hinge side of said door, opposed shoulders on said slide, a guide enveloping said slide between said shoulders, a slide-extension hingedly connected to the outer end of said slide, and an operating-lever pivotally connected with said slide extension.

2. In combination in a door-operating mechanism, an operating-shaft including a rotatable section and a non-rotatable section suitably mounted with ends abutting, a sleeve fast on said rotatable section and enveloping the abutting end portion of said non-rotatable section and having clutchteeth at the end of its enveloping portion, a

collar loose on said non-rotatable section and having clutch-teeth opposed to those of the sleeve, an arm extending from said collar, a clutch-member shiftable on said nonrotatable section between said collarand sleeve and having clutch-teeth arranged to engage the teeth of either of them, an operating-arm on said clutch member, an arm fixed to said rotatable section, an operatingrod connected therewith, an operating-rod connected with said collar-arm, and a dooroperating lever connected with each of said operating-rods.

In testimony whereof I aiiix my signature in presence of two witnesses.
